Verdict

Insufficient data. While the patent remains with an operating company (Western Digital Technologies Inc.) and shows no signs of transfer to a known NPE, the activity consists primarily of an initial assignment from inventors and a security interest followed by a release. There is no information regarding any assertion of this patent, making it difficult to definitively classify its current use.
